for ultimate stability you do well tracking Squeeze.
As for me, well i'm no good example
My LMDE tracks sid with pkgs from aptosid and mepis and as far as it goes i couldn't break it
But for me, computers is an hobby, i don't do here any really work (that one, my work, has nothing to do with computers).
As for suspend/resume i don't use it, so can't help you there but please do open another topic and someone here will look closer into it.
